I am new to the Marlin Owners forum and was wondering how to tell if the 1895 I have purchased is a true pre-Remington gun. It is an 1895 sbl with JM stamped on the barrel, but the serial starts with 91xxx. I have done some research and found that even though it has the JM stamp it still could be a "marlington"? Does anyone have any guidance for me? Any help would be appreciated, thanks.
